Obsolescence of Satchwell AZ2401 Rotary Actuator
The Satchwell AZ2401 actuator would normally have been installed on a Satchwell MBF Valve Body.
The Actuator comprised a 6 wire electrical connection enabling it to be operated from a Satchwell Z Monotronic or CZT Climatronic Proportional Controller as follows :-
Terminal 1 – Open signal
Terminal 2 – Close signal
Terminal 3 – Common
Terminal A – 135 ohm Feedback Potentiometer – winding
Terminal B – 135 ohm Feedback Potentiometer – wiper
Terminal C – 135 ohm Feedback Potentiometer – winding
If all 6 wires are connected then the AZ2401 actuator may be replaced by following SE actuators :-
MD20B-24 + Linkage Kit 914-1070-000 from Schneider Electric and an accessory kit P140A from Belimo
If only 3 wires are connected, that is to terminals 1, 2 and 3 then the P140 accesory kit is not required.
